String tension, measured in kilograms or pounds, has a direct influence on racquet performance. A higher tension improves control, but can reduce power and comfort. Conversely, a lower tension increases power and spin (lift), but can reduce control. This science of optimisation is also studied in detail as part of the Mouratoglou Academy‘s tennis studies programme, where each student is coached to fine-tune his or her settings according to his or her playing style. The professionals adjust these parameters to optimise their specific playing styles.
